People who are healthy and strong have more energy in their hearts and different spirits, so their happiness in life and study will be stronger, and it will be easier to set lofty aspirations and ambitions, while those who are weak will only "look at the ocean and sigh"! Sick people are always weak-willed, easily tired, hard-working and have limited ability to persist in doing things. In short, they will envy other people's "great achievements", but unfortunately they can't do it themselves!
However, physical condition is not static! Some people are born with a good foundation, but they develop bad habits the day after tomorrow, such as smoking, drinking and overeating, which will eventually cause great harm to their health, thus getting worse and worse, even to the point of chronic diseases. And some people, born weak, know how to protect themselves, strengthen exercise, work and rest, eat well, and their bodies will get better and better!
Therefore, if you want to achieve something, you must start with a good analysis of your physical condition!
